IMPROVEMENT IN LIME-KILNS.

Specification forming part of Letters Patent No. 129,617, datedJuly 16,1872.

To all whom it may concern:

Be it known that I, WILLIAM P. STUART, of Hannibal, in the county ofMarion and State of Missouri, have invented a new and valuableImprovement in a Lime-Kiln; and I do hereby declare that the followingis a full, clear, and exact description of the construction andoperation of the same, reference being had to the annexed drawing makingapart of this specification, and to the letters and figures of referencemarked thereon.

Figure 1 of the drawing is a representation of a vertical centralsection of my invention, and Fig. 2 is a horizontal section of the same.

This invention has relation to lime-kilns; and consists in theconstruction and novel arrangement of draught-flues, as hereinafterdescribed.

In the drawing, A represents the cupola having in the lower part thefour fire-boxes B. O is a square base, constructed with an inclinedash-pit, d, in the middle part of each side, located directly under thefire-box of the corresponding side of the cupola. D designates thegrate-bars. The construction of the ash-pits causes the ashes to keepclear of the grate-bars, lessening thereby their liability to burn outso soon and keeping the draught-space clear. E represents thedraught-flues, extending from each side of the cupola to thefiredesignates the kiln-hearth; G, pillows to keep the rock out of theflues and fire-boxes.

What I claim as my invention, and desire to secure by Letters Patent, is

In a lime-kiln having a fire-box, B, at each of its front sides, thedraught-flues E, arranged at right angles to the respective fire-boxesinto which they open, together with the inclined ash-pits d and thepillars Gr, constructed and arranged substantially as specified.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.

W. P. STUART.
